The Lowdown

Alright, Rusty here, checking in. Let’s take a look at what’s cooking over the next couple of weeks at Jaconé.

We’ve got some solid swell on the way, but it’s a mixed bag with the winds. The first few days are the main event, with some serious size and energy rolling in. The water temp is sitting at 72°, which is pretty much bang on average for this time of year, so no surprises there.

The standout is Thursday the 27th. We’ve got a solid 8ft S swell, with a 14-second period, pumping in a massive 2167 (combined energy) of juice. That’s a lot of power. The wind is a clean cross-off from the ENE in the morning, meaning the face will be smooth and inviting. This is serious stuff – over 8ft, so it’s expert territory. If you’re not on your A-game, give it a miss. The crowds are sometimes a thing here, so expect a few others who know what they’re doing.

Friday the 28th is a good follow-up, but a step down in size. The morning has a 4ft S swell, with a 12-second period, and the wind is pure offshore from the ENE at 9 mph. That’s a clean, lined-up wave. The energy is a moderate 610 (combined energy). Good for a solid session.

Then we hit a bit of a lull. Saturday the 29th has a short-period 6ft ENE wind swell in the morning, but it’s only 8 seconds, so it’ll be a bit crumbly, though the offshore NE wind at 6 mph will keep it clean. The afternoon drops right off.

Sunday the 30th and Monday the 31st see a rebound. Monday morning delivers a 7ft ENE swell, again short period at 8 seconds, but with clean offshore NE wind. The energy is a punchy 828 (combined energy). Not the best shape, but plenty of push.

After that, things get messy. From Tuesday the 1st of September right through to the 8th, the wind is mostly onshore or cross-on, and the swell is small and weak. There are a few clean windows in there, like the 4th of September morning with a 6ft S swell, an 11-second period, and offshore ENE wind – that’s a good one for the experienced crew, with 739 (combined energy). The 8th of September morning looks glassy with a 3ft S groundswell at 13 seconds, but it’s pretty small.

The second week is a slow grind. The 10th of September has some size jump in the swell period (13 seconds) and energy (418), but the wind is onshore, so it’s a write-off.

* The Pick: Thursday 27th August morning – 8ft S swell, 14-second period, clean cross-off wind. Big, powerful, and for experts only.
* Best of the Rest: Friday 28th August morning – 4ft S swell, offshore wind, clean. Also Monday 31st August morning for a punchy, if short-period, wave.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
